Deadline broke the news of both castings, noting that Livingston will play Roy Phillips, a wealthy out-of-town businessman who catches the eye of Gillian Darmody (Gretchen Mol), while Geraghty has landed the role of Loren Knox, a prohibition agent with ulterior motives newly assigned to Atlantic City.

Both actors have worked with HBO on the past. Geraghty had a recurring role on the most recent season of “True Blood” (in that horrible Iraq storyline with Scott Foley), and Livingston was recurring on “Sex and the City” (as the infamous Post-It guy) and part of the cast of “Band of Brothers” and “Game Change.”
